What the catalog entry identifies
The filename combines the ES 350 model, 2GR-FE engine, six-speed automatic configuration and complete calibration identifier. It carries no stock or modified variant label and does not name a particular feature or repair. The identifier alone does not establish what changed in this revision or which individual vehicles are compatible.
